and State of Pennsylvania, have invented certain Im rovements in Moving-Picture- Projecting achines, of which the following isfa specification.

"1, l 11s invention is a moving picture projecting machine comprising means for covering and uncovering t e aperture through which light is passed from the lantern to throw upon the screen the pictures on the film moving past the aperture,- and means for adjusting the film with relation to the aperture.

Objects of the improvement are to prop-- erly adjust the relation of the aperture and the pictures upon the film traveling through the machine and to shield the film against flame from the lantern and other sources.

Further objects are to provide for the periodic obstruction of the light by a shutter moving at right angles across the light aperture and to simplify the general mechanism of the machine. In the accompanying drawings, Figure 1 is a side elevation of a machine embodying my improvements; Fig. 2 is a front elevation of the same with parts broken away for clearer illustration, and Fig. 3 is a rear sectional elevation with parts removed for clearer illustration. I

,As shown in the drawings, the machine frame 1 carries the journaled hollow driving shaft 2 having fixed thereon the-spur wheels 3 and 4. A shaft 5 is movable longitudinally within the shaft 2 and is fixed so that it can not revolve relatively thereto by means of the screw 6 passing through the slot 7. The screw 6 fixes to the rod 5 a sleeve 8 movable .longitudinally on the hollow shaft 2, the sleeve having a hub 9. A coiled spring 10,

' held at one end by the bearing 11 fixedto the shaft 2 and engaging at the other end the screw 6, acts to move the sleeve with the shaft to which it is fixed in the direction of the arrow. A coiled spring 12 in the hub 9 is adapted-for acting against a disk 13 on the shaft 2, the movement of the sleeve toward the disk causing the latter to be forced against a wheel 14 normally loose on the shaft 2 and adapted to be clutched between the disk 13 and a disk 15 fixed on the shaft.

I A handle 16, counterbalanced by a weight 17 adjustable on a rod18, islongitudinally fixed to and'movable revolubly on the rod 5. The handle has a hub 19 revoluble on a bushing 20, which is fixed to the wheel 4, and a cam way 21 containing a pin 22 fixed to the bushing. In this construction, when the handle 16 is turned in the direction of the arrow, the engagement between the cam way 21 and the pm 22 causes the shaft 5 and the sleeve 8 to move longitudinally, with the result that the wheel 14 is grip ed between the disks 13 and 15. When t e handle is released the spring 10 moves the shaft 5 and sleeve 8 in the reverse direction to release the wheel 14.

A chain 23 is fixed at one end to the wheel 14 and at the other end to an arm of a lever 24 having the fulcrum 25. The other arm of the lever has thereon a weight 26 and is connected by a hook 27 with a screen 28'. The screen has the guides 29 movable on the ways 30 which are carried by the door 31, and is movable across the a erture 32 in the door. The latter is pivota y connected by the hinges 33and the in34 to bearings 35 of the frame 1, being hdid by a clip or button 37 which is carried by a pivot 38 connected to the frame.

The spur wheel 3, acting through the idler past the aperture 32 and through the way 46 to the bottom sprockets 47 on the shaft 48. The sprockets 49, which give the step by step movement to the film, are carried by the shaft 50 journaled' in the carriage 51- and having thereon a wheel 52. A revoluble shaft 53, journaled in the carriage, has fixed thereon a star wheel 54 with which the wheel 52 engages so as to give to the sprockets 49 the desired step by step movement, -in the usual manner. The shaft 53 has on one end thereof the fly wheel 55 and on the other end a pinion 56 which meshes with the s ur wheel 57. The wheel 57 and a spur whee 58 fixed thereto are journaled on thespindle 59 carried by the carriage. The wheel 58 meshes withthe spur wheel 4 which drives it, and, through the parts described, the shaft 53. It is -to be understood that the carriage 51 can be moved through the vertical range re uired without disengaging the pinion 58 an the gear 4 owing to the relatively large diameter of the latter and the ilic Ll ii an? V.
